- the entire folded edge portions have the backlash continuously.
- the folding stroke S1 should have some amount of margin therein and be long enough to have the folded portions 36 move in the shade guide rails 35 parallel thereto without having any wrinkles on the front shade 31A.
- a length L by which the edge portions are folded over is set to, for example, about 10 mm
- the folding stroke S1 needs to be at least about 10 cm long, which means that the length of the inclination displacement space S in the longitudinal direction of the vehicle needs to be equal to or greater than 10 cm.
- the sunroof apparatus 1 described above if having the driving motor M in front of the front winding shaft 32A, needs to include a space for the driving motor M, a space for the front winding shaft 32A and the inclination displacement space S all in front of the indoor opening 26 arranged in series in the longitudinal direction of the vehicle. This causes the risk that the indoor opening 26 cannot be made large enough.
- the driving motor M is disposed within the inclination displacement space S, more specifically within the folding stroke S1 (shown in diagonal lines) in the longitudinal direction of the vehicle.
- the space for the front winding shaft 32A and the inclination displacement space S which serves also as the space for the driving motor M. This eliminates the need for providing a separate space for the driving motor M in the longitudinal direction of the vehicle. Consequently, the indoor opening 26 can be made large.

Description
- The present invention relates to a sunroof apparatus for a vehicle as described e.g. in
DE 10101491 . - Examples of conventional sunroof apparatuses include an apparatus described in Japanese Unexamined Patent Application Publication No.
2006-131163 patent publication 1 discloses a construction in which the driving motor is disposed in front of an opening formed in the fixed roof. - Examples of shades each disposed below a roof panel include a so-called roller shade which is wound in the form of a roll around a winding shaft and contained (See, for example, Japanese Unexamined Patent Application Publication No.
2010-36898 patent publication 2 describes a technique of folding, when the shade is drawn from a winding shaft, opposite edge portions of the shade before guiding those edge portions in shade guide rails. This technique makes it impossible for the edge portions of the shade to come easily off from the shade guide rails. The edge portions of the shade that are folded have a backlash force to get back to their initial shape. The entire folded edge portions have the backlash force continuously. Thus, even if, for example, an external load is applied to part of the edge portions of the front shade to make that part almost come off from the shade guide, the backlash force in the areas of the edge portions that are adjacent to that part acts to prevent that part from coming off from the shade guide rail. - Japanese Unexamined Patent Application Publication No.
2008-137628 - Regarding the layout of a driving motor for a roof panel and a winding shaft for a shade, these components should be displaced in relation to each other in a longitudinal direction of a vehicle since it is difficult to dispose them in vertically aligned relation to each other from the view point of space-saving in a sunroof apparatus. Although the present inventor was not able to find appropriate prior art documents on the layout of the driving motor and the winding shaft, he has noticed that if the roller shade of, for example, the
patent publication 1 is applied to the construction disclosed in thepatent publication 2 in which the driving motor for the roof panel is disposed in front of the opening, it is resulted that the driving motor and the shade winding shaft are arranged in the longitudinal direction of the vehicle. In that case, it is important that a predetermined amount of distance is ensured between the opposite ends of the opening in arranging the driving motor and the winding shaft. - The present invention is made in view of the above problem, and an object of at least the preferred embodiments of the present invention is to provide a sunroof apparatus that realizes a mitigation in a reduction in the distance between the opposite ends of the opening, the reduction derived from the layout of a driving motor for a roof panel and a winding shaft for a shade.
- The present invention provides a sunroof apparatus comprising: a roof panel disposed in a fixed roof of a vehicle, for being moved in a longitudinal direction of the vehicle via sliders to be opened and closed, the sliders coupled to driving wires; a driving motor for driving the driving wires; and a shade wound into a roll shape around a winding shaft, to be drawn from the winding shaft, passed through an inclination displacement space, and then guided in shade guide rails, for being moved in the longitudinal direction of the vehicle and thereby opening and closing an indoor opening, the inclination displacement space being inclined relative to a horizontal plane and formed between the winding shaft and the shade guide rails, wherein the driving motor is disposed within the inclination displacement space in the longitudinal direction of the vehicle, and wherein the driving motor is located between the winding shaft and the shad guide rails, and above the shade.
- In the so-called roller shade, it is inevitable that the inclination displacement space is formed between the shaft and guide rails in a drawing route of the front shade, the area immediately adjacent to where the front shade gets off from the winding shaft. The present invention utilizes the inclination displacement space as a space for the driving motor such that the inclination displacement space serves also as the space for the driving motor in the longitudinal direction of the vehicle. Consequently, the indoor opening can be made large enough by the space otherwise exclusively occupied by the driving motor.
- The above-mentioned sunroof apparatus preferably has a feature that the shade has an edge portion, the edge portion folded in the shade guide rail when the shade is guided, the edge portion being folded while passing through a folding stroke formed within the inclination displacement space.
- According to the above constitution in which the shade has opposite edge portions folded in the shade guide rails when the shade is guided, the indoor opening can be made large enough.
- The above-mentioned sunroof apparatus preferably has a feature that the winding shaft comprises a pair of a front winding shaft and a rear winding shaft disposed with the indoor opening sandwiched therebetween, and the shade comprises a front shade and a rear shade wound around the front winding shaft and the rear winding shaft, respectively, the front shade and the rear shade abutting on each other midway between opposite ends of the indoor opening to close the indoor opening, and wherein the driving motor is disposed within either one of the inclination displacement space in the front shade and the inclination displacement space in the rear shade.
- In the case of a sunroof apparatus with a single winding shaft, allowance can be provided in the layout design around the indoor opening if, for example, a driving motor for a roof panel is arranged in a front side of a vehicle and the winding shaft is arranged in a rear side with an indoor opening sandwiched between the driving motor and the winding shaft. In the case of a sunroof apparatus in which the winding shaft comprises a pair of a front winding shaft and a rear winding shaft arranged with the indoor opening therebetween, however, the driving motor and either one of the front winding shaft and the rear winding shaft should be arranged side by side, imposing constraints on the layout design around the indoor opening. In contrast, in the above constitution, in which the driving motor is disposed within either one of the inclination displacement space in the front shade and the inclination displacement space in the rear shade, the above constraints are lessened. Consequently, the indoor opening can be made large enough.
- Other features and advantages of the present invention will become more apparent from the following detailed description of a preferred embodiment of the invention, which is described by way of example only and with reference to the accompanying drawings.

The second coupling pins 21 are rotatable and movable along the rear guide rails 10. The linkingarm 19 has a secondlift guide pin 22 at the middle thereof. The second lift guide pins 22 are slidably engaged with secondlift guide grooves 23 formed in therear sliders 8. - From the fully closed state of the
roof panel 3 shown inFIG. 3A , thefront sliders 7 and therear sliders 8 are moved rearward as a unit by the driving force of the driving motor M (FIG. 2 ) via the push-pull cables 11, when the inner walls of the firstlift guide grooves 16 push the first lift guide pins 15 upward and the inner walls of the secondlift guide grooves 23 push the second lift guide pins 22 upward to erect the linkingarms 19 as shown inFIG. 3B and 3C , thereby tilting up theroof panel 3. After the completion of the tilting up, thefront sliders 7 and therear sliders 8 move further rearward. This causes the inner walls at the respective ends of the firstlift guide grooves 16 to push the first lift guide pins 15 rearward and the inner walls at the respective ends of the secondlift guide grooves 23 to push the second lift guide pins 22 rearward thereby to move theroof panel 3 rearward as shown inFIG. 3D . It should be noted that during the movement of theroof panel 3, thesecond panel brackets 17 and the linkingarms 19 pass in the gaps between the fixedpanel 4 and the side garnishes 6. - Descriptions will be made of the
shade 31. As shown inFIG. 5 , theshade 31 is a so-called roller shade which is wound in the form of a roll around a winding shaft and contained. Theshade 31 is made of a flexible material. In the embodiment, theshade 31 is of a type divided into two: afront shade 31A and arear shade 31B. To harmonize with the use of theshade 31 of this type, windingshafts 32 are disposed as a pair of a front shaft and a rear shaft with theindoor opening 26 sandwiched theretween. That is, afront winding shaft 32A that winds thefront shade 31A therearound is disposed in front of theindoor opening 26 with the axis of the front windingshaft 32A set in the transverse direction of the vehicle, while arear winding shaft 32B that winds therear shade 31B is disposed behind theindoor opening 26 with the axis of therear winding shaft 32B set in the transverse direction of the vehicle. As shown inFIG. 2 , thefront winding shaft 32A and therear winding shaft 32B are both rotatably supported byholders 37 secured to unillustrated brackets. - As shown in
FIG. 5 , thefront shade 31A and therear shade 31B are made to abut on each other, more specifically, afront handle 33 and arear handle 34 on their respective edges are made to abut on each other, midway between the opposite ends of theindoor opening 26 to close theindoor opening 26. Shown in phantom in the figure is where thefront handle 33 and therear handle 34 are positioned when theindoor opening 26 is fully opened.Reference numeral 38 signifies a roof lining covering the vehicle interior ceiling. It should be noted that a description is omitted of a mechanism of holding thefront shade 31A and therear shade 31B at given opening positions since it departs from the purpose of the present invention. - As shown in
FIGs. 2 ,4 ,7A and 7B ,shade guide rails 35 are disposed more inwardly from the front guide rails 9. Theshade guide rails 35 are made of, for example, an extruded aluminum alloy. As shown inFIGs. 7A and 7B ,slide shoes 33A are engaged with theshade guide rails 35 slidably in the longitudinal direction of the vehicle. The slide shoes 33A are provided projectingly on the sides of thefront handle 33. Similar slide shoes (not illustrated) are provided projectingly on the sides of therear handle 34. - As shown in
FIGs. 6 ,7A and 7B , theshade guide rails 35 have multifunctionstoppers 39 on their front edges. Themultifunction stoppers 39 comprise, for example, resin molded parts. Themultifunction stoppers 39 are members that have both the function of positioning thefront handle 33 by abutting on theslide shoes 33A when thefront shade 31A is fully opened, and the function of smoothly guiding the movement of thefront shade 31A between an inclination displacement space S to be described later and the shade guide rails 35. - The roller shade structure in which the
front shade 31A is wound around thefront winding shaft 32A and contained has the inclination displacement space S that is inclined relative to a horizontal plane when viewed from the side as shown inFIG. 6 . The inclination displacement space S is formed between the front windingshaft 32A and theshade guide rails 35 in a drawing route of thefront shade 31A. InFIG. 6 , the route is shown in full lines when thefront shade 31A is wound in a greater amount on thefront winding shaft 32A, while the route is shown in phantom lines when thefront shade 31A is wound in a smaller amount. - Thus, it is inevitable that the inclination displacement space S is formed between the front winding
shaft 32 and the shade guide rails 35. If a length of the inclination displacement space S in the longitudinal direction of the vehicle, that is, a distance between the front windingshaft 32A and theshade guide rails 35, is reduced, a tilt angle θ formed with thefront shade 31A increases. The increase in the tilt angle θ causes an increase in a quantity of a vertical component of a tension force on a portion of thefront shade 31A that extends the length of the inclination displacement space S in the longitudinal direction of the vehicle. This induces an increase in a loss in a quantity of a horizontal component of a load assumed in operating the front handle 33 (FIG. 5 ). As a result, a greater amount of manual force is required for moving thefront handle 33. This is why there should be a certain amount of margin in the length of the inclination displacement space S in the longitudinal direction of the vehicle. Especially when a folding stroke S1 is formed as described later, the inclination displacement space S should be equal to or greater than the folding stroke S1 in length in the longitudinal direction of the vehicle. - In the embodiment, the
front shade 31A drawn from the front windingshaft 32A is passed through the folding stroke S1 before being guided in theshade guide rails 35 to open and close theindoor opening 26 in the longitudinal direction of the vehicle. The folding stroke S1 is formed within the inclination displacement space S. In the folding stroke S1, opposite edge portions of thefront shade 31A are folded so that thefront shade 31A is guided with the opposite edge portions folded in the shade guide rails 35. The edge portions of thefront shade 31A which are formed into upwardly foldedportions 36 and which are guided in the grooves of theshade guide rails 35 as shown inFIG. 4 have a backlash which acts to let the edge portions get back to their initial shape. The entire folded edge portions have the backlash continuously. Thus, even if, for example, an external load is applied from inside the vehicle to part of the edge portions of thefront shade 31A, the backlash force in the areas of the edge portions of thefront shade 31A that are adjacent to that part acts to prevent that part from coming off from theshade guide rail 35. Thus, it is impossible for the edge portions of thefront shade 31A to come easily off from the shade guide rails 35. The same holds true for therear shade 31B. - In the structure in which the edge portions of the
front shade 31A are folded in mid-course after being drawn from the front windingshaft 32A, the folding stroke S1 should have some amount of margin therein and be long enough to have the foldedportions 36 move in theshade guide rails 35 parallel thereto without having any wrinkles on thefront shade 31A. When, a length L by which the edge portions are folded over is set to, for example, about 10 mm, the folding stroke S1 needs to be at least about 10 cm long, which means that the length of the inclination displacement space S in the longitudinal direction of the vehicle needs to be equal to or greater than 10 cm. - The
sunroof apparatus 1 described above, if having the driving motor M in front of the front windingshaft 32A, needs to include a space for the driving motor M, a space for the front windingshaft 32A and the inclination displacement space S all in front of theindoor opening 26 arranged in series in the longitudinal direction of the vehicle. This causes the risk that theindoor opening 26 cannot be made large enough. - In contrast, in the present invention, as shown in
FIGs. 6 ,7A and 7B , the driving motor M is disposed within the inclination displacement space S, more specifically within the folding stroke S1 (shown in diagonal lines) in the longitudinal direction of the vehicle. Thus, necessary to be provided in front of theindoor opening 26 are only the space for the front windingshaft 32A and the inclination displacement space S which serves also as the space for the driving motor M. This eliminates the need for providing a separate space for the driving motor M in the longitudinal direction of the vehicle. Consequently, theindoor opening 26 can be made large. It should be noted that there is no need for the driving motor M to be entirely accommodated within the inclination displacement space S, and part of the driving motor M may be disposed more or less outside the inclination displacement space S. The driving motor M, below which thefront shade 31A is positioned, is attached to and supported by unillustrated brackets positioned above the driving motor M. Theguide pipes 12 is also laid above thefront shade 31A in order not to interfere with thefront shade 31A. - In the above, descriptions have been made of a preferred embodiment of the present invention. In the illustrated embodiment, the driving motor M is disposed within the inclination displacement space S in the
front shade 31A. In the case where the driving motor M is disposed behind theindoor opening 26, however, the driving motor M may be arranged within the inclination displacement space S in therear shade 31B. - Further, the present invention is also applicable to a sunroof apparatus with a
single shade 31. - The present invention utilizes the inclination displacement space formed between the shaft for winding the shade and the shade guide rail as the space for the driving motor, eliminating the need for providing a separate space for the driving motor. Consequently, the indoor opening can be made large enough.
- The embodiment of the present invention has been explained as aforementioned. However, the embodiment of the present invention is not limited to those explanations, and those skilled in the art ascertain the essential characteristics of the present invention and can make various modifications and variations to the present invention to adapt it to various usages and conditions without departing from the scope of the claims.
